- * NXP PCA PCA9564/PCA9665 I2C controller
- The PCA9564/PCA9665 serves as an interface between most standard
- parallel-bus microcontrollers/microprocessors and the serial I2C-bus
- and allows the parallel bus system to communicate bi-directionally
- with the I2C-bus.
- Required properties :
- - reg : Offset and length of the register set for the device
- - compatible : one of "nxp,pca9564" or "nxp,pca9665"
- Optional properties
- - interrupts : the interrupt number
- - reset-gpios : gpio specifier for gpio connected to RESET_N pin. As the line
- is active low, it should be marked GPIO_ACTIVE_LOW.
- - clock-frequency : I2C bus frequency.
- Example:
- i2c0: i2c@80000 {
- compatible = "nxp,pca9564";
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0x80000 0x4>;
- reset-gpios = <&gpio1 0 GPIO_ACTIVE_LOW>;
- clock-frequency = <100000>;
- };
